The Rival was electric only I think and the MGT was nitro only. At least as far as I'm aware. The two were a lot alike though not identical.... I mean even outside the fact that was is electric and one is nitro
Its an Associated MGT4.6.
The MGT4.6 was a virtually identical clone of the the Thunder Tiger MTA4. What gives it away here is the flame pattern on the factory body and the MGT4.6 had a blue cooling head as opposed to the red one on the MTA4.
